	S.M. Liuzzo, N. Carmignani, J. Chavanne, L. Farvacque, B. Nash, P. Raimondi ESRF, Grenoble, France
	The ESRF-EBS project foresees the replacement of the existing bending magnets beamlines with different radiation sources: short bend, 2-pole wiggler or 3-pole wiggler. After describing the reasons for this choices the required modifications to the storage ring lattice are described in details for each case. The study of the impact of lattice errors is also addressed, leading to the definition of beamlines' alignment tolerances.

MOPIK063	Non-Linear Kickers Using Eddy Current Screens and Application to the ESRF	670
	S.M. White, M. Dubrulle, L. Farvacque, P. Henrissat, G. Le Bec, E. Plouviez, P. Raimondi, C. Richard ESRF, Grenoble, France
	The ESRF storage ring injection and accumulation is performed using standard 4-kickers bump and septum magnet. Sextupoles are located within the injection bump leading to significant bump non-closure during the ramp-up and ramp-down and optics distorsion for both stored and injected beam. Introducing non-linearities in the kickers allows for compensation of the perturbation from these sextupoles. We report on the feasibility of adding eddy current screens to a standard kicker magnet design to generate a non-linear field and its recent application to mitigate the injection perturbations at the ESRF.

	We are studying a new scheme to produce very low emittance muon beams using a positron beam of about 45 GeV interacting on electrons on target. This is a challenging and innovative scheme that needs a full design study. One of the innovative topics to be investigated is the behaviour of the positron beam stored in a low emittance ring with a thin target, that is directly inserted in the ring chamber to produce muons. Muons will be immediately collected at the exit of the target and transported to two mu+ and mu- accumulator rings. We focus in this paper on the simulation of the e⁺ beam interacting with the target, its degradation in the 6-D phase space and the optimization of the e⁺ ring design mainly to maximize the energy acceptance. We will investigate the performances of this scheme, ring optics plus target system, comparing different multi-turn simulations.
